SCREW-OPERATED PIVOTED-JAW BOLT HOLDER.

Filed Aug. 25, 1947 Inventor Arno/d Stacey Patented Aug. 15, 1950Arnold" Sjtacey; Jasper; Ark? This. invention relates .to new...and.usefulirm. provement in. a combination .lboltlholder and nbeaine,and-battery terminah puller and the primary object of the presentinvention is;..to.pr;o-=. videatdevice -whicmwill engage the kerf of abolt to hold the same against rotation as the nut is being screwedqon oroff of the; bolt.

Another important object .of the. present invention is to provide adevice of the aforementioned character so designed as to be used inpulling or removing battery terminals, gears, and b in svfrom shaftsandthelike in a minimum time.

A.further object of the presentinventiomis-to provide-a combination bolthelder, gear,- heari-n'gand battery terminal.puller..-that is; quicklyand readily applied to the article on which the same is to be used.

A still further aim of the present invention is to provide a device ofthe class described that is simple and practical in construction, strongand reliable in use, relatively inexpensive to manufacture, andotherwise well adapted for the purposes for which the same is intended.

Other objects and advantages resid in the details of construction andoperation as more fully hereinafter described and claimed, referencebeing had to the accompanying drawings forming part hereof, wherein likenumerals refer to like parts throughout, and in which:

Figure 1 is a side elevational view of the present combination tool;

Figure 2 is a top plan view of Figure 1;

Figure 3 is an enlarged longitudinal vertical sectional view takensubstantially on the plane of the broken section line 3--3 of Figure 2;and

Figure 4 is an enlarged longitudinal horizontal sectional view taken onsubstantially on the plane of section line 4-4 of Figure 3.

Referring now to the drawings in detail, wherein for the purpose ofillustration, there is disclosed a preferred embodiment of the presentinvention, the numeral represents a pair of substantially rectangularforwardly converging side members having an integral sleeve I2 formed attheir forward portions that engages a cylindrical support member [4. Arivet or the like l6 connecting the forward ends of the side membersengages a transverse recess [8 provided in the member l4, to preventmovement of the member l4 relative to the sleeve.

A vertical and preferably square bore is provided in the member 14 andslidably engages the square shank portion 22 of a, kerf engaging member24. A set screw 26 adjustably mounted emaemamm, 1947;.'SerialeNo;HWAJHv,

Projec ed upwardly fromthe' rear portion. of: the side members ,I D,Tisia. pair ot. Spacedbarallli" extensions 4z"tha.t-.,a'reintegrallyl-fb 'medi the side members. The upper terminals of theextensions 42 are pivoted as at 44 to a pair of arcuate links 46 thatare rigidly carried by a travelling block 48 adjustably mounted on therod 38. The free terminals of these extensions 42 project forwardly andthe upper and lower edges of these terminals are bent inwardly upon eachother to provide a pair of forwardly diverging movable jaws 50 that areadjustable toward the member 24 when the rod 36 is r0- tatecl to movethe block .48 toward the hand rib 4%]. In practical use of the device,for holding bolts, the kerf in the head of a bolt (not shown) is engagedby the kerf engaging member 24 with the shank of the bolt and nutcarried thereby projecting outwardly between the jaws 56. As the rod 36is rotated to move the traveling block 48 toward the hand grip 40, thejaws will clamp against the structure holding the bolt so that asuitable tool' may be employed for removing or tightening the nut on thebolt with the kerf engaging member holding the bolt against rotation,and the jaws preventing movement of the structure holding the bolt.

Also, the device may be inverted so that the jaws embrace a batteryvpost and extend between a battery terminal and the battery casing (notshown) and the kerf engaging member bears on the battery post. In thisposition, by rotating the rod 40, the kerf engaging member will remainfixed and the jaws will force the battery terminal toward the kerfengaging members for convenient removal of the battery terminal.

Obviously, a like procedure may be used in removing gears, bearings andthe like from shafts.

In view of the foregoing description taken in conjunction with theaccompanying drawings it is believed that a clear understanding of thedevice will be quite apparent to those skilled in this art. A moredetailed description is accordingly deemed unnecessary.

It is to be understood, however, that even though there is herein shownand described a preferred embodiment of the invention the same issusceptible to certain changes fully comprehended by the spirit of theinvention as herein described and the scope of the appended claims.

Having described the invention, what is claimed as new is:

1. A bolt holder comprising a pair of forwardly converging side members,a sleeve formed at the forward terminals of said side members, acylindrical body rigidly carried by said sleeve, 2. kerf engaging memberremovably and adjustably carried by said body, integral extensionsprojecting upwardly from the rear portions of said side members, a pairof movable jaws pivoted on said extensions, and means for actuating saidjaws relative to said kerf engaging, member, said means including ascrew threaded rod pivotally and swivelly mounted on said side members,a traveling block mounted on said rod, and means connecting saidtraveling block to said jaws.

' 21A bolt ho'lder comprising a pair of forwardly converging sidemembers, a sleeve formed at the forward terminals of said side members,a cylindrical body rigidly carried by said sleeve, a kerf engagingmember removably and adjustably carried by said body, extensionsprojecting upwardly from the rear portions of said side members, a pairof movable jaws pivoted on said extensions, and means for actuating saidjaws relative to said kerf engaging member, said means including a pivotpin carried by said side members having a central aperture therein, ascrew threaded rod having a reduced terminal loosely engaging theaperture in said pivot pin, means for retaining said rod in position tosaid pivot pin, a traveling block mounted on said rod, and meansconnecting said traveling block to said jaws.

3. The combination of claim 2 wherein said connecting means includes apair of arcuate extensions integrally formed with said laws.

4. A bolt holder comprising a pair of substantially rectangular sidemembers having forward and rear portions, a sleeve integrally formedwith the forward portions of said side members, a kerf engaging memberremovably and adjustably carried by said body, a pair of spaced parallelextensions projecting laterally from the rear portions-of said sidemembers, a pair of swingable jaws pivoted on said extensions, a pair ofarcuate links integrally formed with said jaws and having rear endportions, a threaded rod swiveled to said side members, and aninternally threaded traveling block secured to the rear end portions oflinks, said traveling block being threaded on said rod;
